Configuring a server with balanced memory is important for maximizing its memory bandwidth and overall performance. Lenovo ThinkSystem servers running second-generation Intel Xeon Scalable processors have six memory channels per processor and up to two DIMMs per channel, so it is important to understand what is considered a balanced configuration and what is not.
This paper defines three balanced memory guidelines that will guide you to select a balanced memory configuration. Balanced and unbalanced memory configurations are presented along with their relative measured memory bandwidths to show the effect of unbalanced memory. Suggestions are also provided on how to produce balanced memory configurations.
This paper is for customers and for business partners and sellers wishing to understand how to maximize the performance of Lenovo ThinkSystem servers with second-generation Intel Xeon Scalable processors.
